Specification of Letters Patent.

Patented Jan. 23, 1917.

Application filed July 9, 1913. Serial No. 778,082.

To all whom it may concern:

Be it known that 1, WILLIAM E. SPARKS, a citizen of the United States,residing in the city and county of New Haven and State of Connecticut,have invented certain new and useful Improvements in Planes, of whichthe following is a full, clear, and exact description.

This invention relates to planes, and more particularly to a novelconstruction of sheet metal planes.

Certain features of my improvements are especially applicable to planesof the smaller sizes which are known as pocket planes or toy planes, butthe invention is not limited in this particular.

The primary object which I have in view is the provision of a light,handy, efficient and durable plane, in which the number of parts isreduced to a minimum, and which can be readily and cheaply manufactured.

To this and other ends, the invention consists in the novel features andcombinations of parts to be hereinafter described and claimed.

In the accompanying drawing, Figure 1 is a side elevation of a planeembodying my improvements, Fig. 2 is a top plan View of the same, Fig. 3is a section on line 3-3 of Fig. 2, Fig. 4 is a front end elevation ofthe plane, Fig. 5 is a rear end elevation thereof, Fig. 6 is a sectionon line 66 of Fig. 1, Fig. 7 is a top plan view of the frog, detached,Fig. 8 is a top plan view of the clamp, and Fig. 9 is a bottom plan Viewof the clamp.

Referring to the drawing, the body or stock 10 is of the usual channeledform and it is preferably constructed of sheet metal. The frog 11 hasthe usual relation with respect to the throat 12 and said frog is constructed of a sheet metal plate l1 having downturned side portions 11fitted within and against the side walls of the stock. In order tosecure the frog firmly in place in the stock, it is necessary to employonly two fastening members such as the rivets 13, 14. These rivets passthrough the extensions 11 of the frog into and through the respectiveside walls of the stock. It will be noted from a comparison of Figs. 1and 3 that the rivets 13, 14 are out of line with each other whereby anyturning or rotary movement of the frog relatively to the stock isabsolutely prevented simply by the use of these two fastening members,one associated with each of the side walls of the stock.

At the rear of the frog the same is provided with integral downturnedlugs 15, 16 provided with threaded perforations for the shank 17 of theadjusting screw 18. The cutter or bit 19 is supported on the frog 11 inthe usual manner and it is of'customary form except for the fact thatits rear extremity is provided with a transverse slot 20 to receive themilled head 21 of the adjusting screw 18. The peripheral portion of thehead 21 extends through the slot 20 for a slight distance, and as theadjusting screw is turned, the head thereof will turn freely in the slot20 thereby advancing or retracting the cutter 19 according to thedirection in which the screw is rotated. In other words, the slot 20 infitting over the head 21 interlocks the cutter and the adjusting screwagainst relative longitudinal displacement while permitting the rotationof the screw relatively to the cutter.

The frog 11 carries a pivot or stud 22, and the cutter is provided withthe usual slot to fit over this stud 22. The clamp 23 consists of asheet metal plate having downturned edges 24 and a keyhole slot 25adapted to cooperate with the stud 22 in the usual manner. At the rearextremity of the clamp 23, the same is provided with a threaded socket26 through which a clamping screw 27 passes into engagement with theupper surface of the cutter or bit. The cooperation between the clampingscrew 27, the clamp 23, the stud 22, and the bit 19 is more or lessusual and need not be further described.

In order to afford a convenient and handy grip for the workman, thestock is provided at the rear end with a palm rest 28. This consists ofan upwardly directed sheet metal plate having a convex rear surface andforwardly extending lugs 29 fitting between and against the side wallsof the stock. The palm rest is substantially U- shaped in cross-section,the upper edge 28 being rounded and the lower edge 28 straight andhorizontal and fitting snugly against the top surface of the bed of thestock. The lugs or extensions 29 are secured to the side walls of thestock by rivets 30, 31 or similar fastening members. The rivets 30, 31are offset from each other as in the case of the rivets 13, 14 so thatturning movement of the palm rest relatively to the stock is absolutelyprevented without the employment of additional fastening means.Preferably, the forwardly and upwardly curved plate 28 forming the palmrest is located at the rear extremity of the plane body or stock, and isspaced from the frog and cutter located'at'the intermediate part of thestock so that the adju'stingscrew may be located between the palm restand cutter. The rear surface of the palm rest curves forwardly in orderto 'fitthe palm of" the operator, and'the form of the palm rest, is suchthat it merges from a shallow U-shaped cross-section'near the top into adeeper U-shaped cross section atthe bottom where the -forwardly directedextensions 29 are provided.

I do not laim herein the combination witha stock havinguprightsidewalls, of afrog comprising a sheet'metal platehaving integraldownturned side memberssecured to'the side walls of the stock, andintegral downturned lugs "for 'the bit adjusting screw, one of said lugsbein'g struck out from the rear edge ofthe frog, and the other beingstruck out of: an opening at'ithe intermediate portion of the'frog, asclaimed in my co-pen'dingapplication, Serial No. 778,088.
